Function Documentation

InitializeUdf()

EFI_STATUS EFIAPI InitializeUdf	(	IN EFI_HANDLE	ImageHandle,
		IN EFI_SYSTEM_TABLE *	SystemTable
	)

The user Entry Point for UDF file system driver. The user code starts with this function.

Parameters

[in]	ImageHandle	The firmware allocated handle for the EFI image.
[in]	SystemTable	A pointer to the EFI System Table.

Return values

EFI_SUCCESS	The entry point is executed successfully.
other	Some error occurs when executing this entry point.

UdfDriverBindingStart()

EFI_STATUS EFIAPI UdfDriverBindingStart	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN EFI_DEVICE_PATH_PROTOCOL *	RemainingDevicePath
	)

Start this driver on ControllerHandle by opening a Block IO or a Block IO2 or both, and Disk IO protocol, reading Device Path, and creating a child handle with a Disk IO and device path protocol.

Parameters

[in]	This	Protocol instance pointer.
[in]	ControllerHandle	Handle of device to bind driver to
[in]	RemainingDevicePath	Optional parameter use to pick a specific child device to start.

Return values

EFI_SUCCESS	This driver is added to ControllerHandle.
EFI_ALREADY_STARTED	This driver is already running on ControllerHandle.
other	This driver does not support this device.

UdfDriverBindingStop()

EFI_STATUS EFIAPI UdfDriverBindingStop	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN UINTN	NumberOfChildren,
		IN EFI_HANDLE *	ChildHandleBuffer
	)

Stop this driver on ControllerHandle. Support stopping any child handles created by this driver.

Parameters

This	Protocol instance pointer.
ControllerHandle	Handle of device to stop driver on
NumberOfChildren	Number of Handles in ChildHandleBuffer. If number of children is zero stop the entire bus driver.
ChildHandleBuffer	List of Child Handles to Stop.

Return values

EFI_SUCCESS	This driver is removed ControllerHandle
other	This driver was not removed from this device

UdfDriverBindingSupported()

EFI_STATUS EFIAPI UdfDriverBindingSupported	(	IN EFI_DRIVER_BINDING_PROTOCOL *	This,
		IN EFI_HANDLE	ControllerHandle,
		IN EFI_DEVICE_PATH_PROTOCOL *	RemainingDevicePath
	)

Test to see if this driver supports ControllerHandle. Any ControllerHandle than contains a BlockIo and DiskIo protocol or a BlockIo2 protocol can be supported.

Parameters

[in]	This	Protocol instance pointer.
[in]	ControllerHandle	Handle of device to test.
[in]	RemainingDevicePath	Optional parameter use to pick a specific child device to start.

Return values

EFI_SUCCESS	This driver supports this device.
EFI_ALREADY_STARTED	This driver is already running on this device.
other	This driver does not support this device.
